SEP 2 4 1940 1 Claim. (CL 290-2) An object of this invention is to provide an efficient form of heating, power and lighting equipment for houses and small buildings of various kinds.

Another object is to combine such equipment with either hot water or steam heating apparatus, as well as providing hot water for domestic use.

These and other objects, as will hereinafter appear, are accomplished by this invention which is fully described in the following specification and shown in the accompanying drawing, in which- The figure is a side elevation partly in section showing the heating and lighting equipment applied to a hot water heating system.

The embodiment illustrated comprises essentially an internal combustion engine A located preferably in the basement of the building to be heated, and adapted to drive an electric generator B, preferably of the alternating current type, the water from the cooling jacket of the engine being drawn from the bottom of a heating tank C and returned to the top of the same, the water in this tank also being heated by the exhaust gases from the engine passing through a coil D in the tank, the hot water from the top of the water tank C passing to heating coils E for heating rooms in a well known manner. Water for domestic use is also heated in a heat transfer coil F and stored in a hot water storage tank G.

The engine A preferably runs continuously at substantially uniform speed and has a storage battery (not shown) for supplying electric current for the ignition. This engine will operate successfully on kerosene or distillate which is stored in an underground tank I and carried to the carburetor of the engine through a pipe H. This tank is filled from out of doors through a filling pipe l2, the tank being vented to the atmosphere through a pipe I3. The engine and generator are preferably mounted on a suitable base i which is mounted on springs I! to absorb vibration of the engine and to prevent noise. The engine is also preferably enclosed in a cabinet or room l6 which is rendered substantially sound proof. A flexible metal exhaust pipe I! extends through the side of this cabinet and connects with the coil D, the opposite end of the coil connecting through a pipe IS with the stack I9 through which the exhaust gas is passed to the atmosphere.

The bottom of the tank C connects through suitable pipes or fittings 20 and a flexible hose 2| with the bottom of the engine cooling jacket, the top of the jacket leading to a pump 22 which is driven in any suitable manner, as by means of a belt 23, from the engine crank shaft. A flexible hose 24 leads from the pump 22 to a riser 23 which leads into the top of the water tank C. Thus when the engine is running a continuous stream of water passes from the bottom of the tank C through the engine cooling jacket and back to the top of the tank, thus heating the water in the tank. The riser 25 extends vertically and has lateral pipes 26 for carrying water to the various radiators E, thereturn from these radiators (of which only one isshown) being through pipes 21, 28. and 20.

Electric current from the generator B is carried to a suitable switchboard 23 which has a distributing line 30 for furnishing power and light to the building. Connected to this is a line 3| which connects to an electric heating unit 32 which extends into the tank C so as to heat the water therein, this heating unit being connected in series circuit with an aquastat 33 of a well known type which is set to close the circuit 3| through the heating coil 32 when the temperature of the water in the top of the tank falls below 180' F. and to open when the temperature of this water reaches 190 F.

A drain pipe 34 connects through an electrically operated valve 33 with the riser 23 and leads to a drain, not shown. The electric control for the valve 35 connects with the line 3| through an aquastat 36 which is set to open the valve when the temperature of the water in the top of the tank exceeds 200 F., and to close this valve again when the temperature of this water falls to say 190 F. The temperature and 35 pressure of the water in the top of the tank C is shown by a combination pressure gauge and thermometer 31. The water in the tank C is supplied through a pipe 38 and controlled by means of an automatic water feeder 39 of a well known The temperature of each individual radiator E may be controlled by means of a valve 40 connected to each radiator, and the water flowing to all the radiators may be controlled by means of a valve ll operated by an electric coil 42 connflcted in series circuit with a thermostat 43 located in some convenient part of the building and connected through a line 44 with the generator. Thus when the temperature at the thermostat exceeds a predetermined amount, the coil 42 closes the valve 4i thereby preventing hot water from passing up the riser 25 to the radiators. The thermostat 43 will be set to' open and close on a temperature differential of 2 to 3 degrees Fahrenheit so as to maintain a substantially uniform temperature.

Hot water {or domestic use is stored in the tank G which has a pipe leading to the bottomof the heat transfer coil 1', the top of this coil connecting through a pipe 16 with the top of the tank G. The coil F may .be located in the tank C or closely adjacent thereto so as to be surrounded with' hot water from the tank. The heat of this water is transferred to the coil F, thereby heating the water within the coil which rises by convection producing a circulation down through the pipe 45 and up through the pipe 4, as indicated by arrows.

When the water in the tank C is quite cold it is desirable that its temperature should be brought up rapidly, and for this purpose I have provided a temperature controlled mechanism,

not shown in detail, having a lever 41 connected through a link 48 with the engine distributor 49, so that when the water-is cold the distributor will be rotated so as to retard thespark sumciently to materially increase the amount otheat transierred to the Jacket water without, how-- ever, materially decreasing the speed of the en-= gine. In this way the temperature of the water in the tank C will rapidly be brought up to a normal temperature 01' to F. at the top or the tank. As soon as the water at the bottom or. the tank reaches a predetermined trolled bythe heat or the rangement may be made which do not depart from thespirit and scope of the invention as disclosed in the appended claim.

I claim:

In combination, an electric generator for fur--v nishing light and power for a building, an internal combustion engine i'or driving the generator, a storage tank for storing hot water for domestic purposes, means including a heating tank ior utilizing the waste heat of the engine to heat the water in the storage tank, the engine having a distributor with a spark advance, means concooling water or the engine for controlling the degree of spar-k ad-' vance.
